Mechanical Advantage sets for Arborists

Arborists spend a lot of time rigging rope down, but sometimes it's necessary to lift a limb or load. With these block and tackle sets, you can generate a serious mechanical advantage in your favor. Some of our arborist block and tackle kits even contain a progress capture device in the system, so that the load won't slip even if you let go of the rope.
